This looks like Muramuraaki's work: I can tell from the level of details in its gore, the little hearts after the piko-piko sfx, the general panel layout, the story title/page number at the bottom, the 'this story is fiction' text at the end and from having translated 2 of his story's.
P.S.: a suspicious looking guy in a hoodie with a bag full of knives? Enjoy getting butt-raped by the cops.
